摘要:

非連續增強鈦基復合材料（DRTMCs）具有高比強度、低密度、優異的耐蝕性等諸多特性，在航空航天、國防工業、交通運輸等領域具有廣泛的應用前景。石墨烯具有良好的本征物理和力學性能，是近年來的二維碳納米“明星”材料，被視為極具潛力的DRTMCs納米增強體。國內外研究者聚焦DRTMCs設計與制備，突破了低溫快速成型和界面改性等關鍵技術，初步實現了界面精細調控和微觀構型，獲得石墨烯在鈦基體中的本征增強，制備出強塑性匹配較好的DRTMCs。簡要綜述近些年來石墨烯增強鈦基復合材料的設計方法和制備工藝，探討界面反應、界面結構、微觀構型等關鍵因素對復合材料力學性能和失效機制的影響規律，并提出石墨烯增強鈦基復合材料未來的發展方向。

Abstract:

Discontinuously reinforced titanium matrix composites (DRTMCs) have many excellent properties such as high specific strength, low density, superior corrosion resistance, which have become ideal candidates for aerospace,defense industry and transportation field and have a wide range of applications. Graphene, as a two-dimensional carbon nano “star” material with excellent intrinsic physical and mechanical properties, has been regarded as a promising nano-reinforcement for DRTMCs in recent years. Recently, domestic and foreign researchers have been focusing on solving the key issue of severe interfacial reaction caused by traditional high-temperature sintering through rapid low-temperature consolidation as well as powder modification,established a precise interface control method for graphene-reinforced Ti composites, and optimized the configuration to realize the graphene nanoplatelets intrinsic strengthening. The present work summarized the fabrication and design method of graphene reinforced titanium matrix composites in recent years,investigating the effects of interface reactions, interface structure and micro-configuration or other key factors on the mechanical properties, failure mechanism, and prospected the development trend of graphene reinforced titanium matrix composites in the further.
